10 Claims. (Cl. 128-141) This invention relates to a new andimproved goggle device particularly characterized by sub-- stantial freedom from fogging of the lens.

A primary object of the invention 'isto provide a goggle device comprising'a main frame portiondefining an eye chamber and a supplemental frame portion or "nose piece connected-to said main frame portion by means providing communication for-air therebetween,- and wherein the natural breathing of the wearer-of said device provides forced ventil'ationof said eye chamber.

A morespecific object is to-provide a goggle device as outlined above incorporating valve means acting to permit air to passthrcugh from said eye chamber tosaid nose piecebutto prevent exhaled air from returning to said eye chamber.

A further objeet is to provide-a goggle device as outlined abovewh'erein said nose piece-is de-i tachable from said main frame portioni without affecting the function orvoperation. of said main frame portion. i

Still further objects randladvantages will in part appear and "in part ;be pointed-out in the course of the followingdetailed descriptionof one or more embodiments of .the" invention, which are given as nonlimiting examples inz connection with the accompanying. drawings, inwhicl'i:

Figure 4 is a topview partly in section substan.-. tially on the line 4--4 in Fig. 1;

Figure 5 is a fragmentary rear viewbpartly broken away; and

Figure 6 is arbottom view of the novel nose piece of the invention.

The goggle of the present invention comprises essentially a main goggle frame I0 providing the eye chamber and. a supplemental frametor nose piece ll. Main frame [0 comprises-a rim portion 12 holding lens I4, and a, rearwardly extending portion l5 terminating in flange portion l6 which engagesthe face of the wearer.. Frame I0 is preferably formed of .natural or synthetic rubber or other resilient material and flange I6 is therefore preferably stippled,,lined with chamois, flocked or otherwise. treated as indicated at l8 for greater comfort. Lens "'15 preferably material incorporated therein.-

formedof a transparent organic-plastic,.such for exampleaas cellulose acetate, and may ifdesired have a dye or other selectively light-absorbing Lens l4-may be mounted in rim l2 in anyconvenient Way; for example, it is-shown as-engaging in a slot within rim: I2 and retained therein by'means of snap fasteners 20 and 22 carried by-the walls of said slots At-its outer ends,,lens;l4 is provided with slots 24 adapted to receive head straps 25; -As isshown particularly cin Figs. 1 and'4', slots '24 are preferably T-shaped. to facilitate removal of straps-25 therefrom for exchanging lenses and may be reinforced. by means'of grommets 26. Straps 25are provided with enlarged ends 28-to prevent withdrawal through slots 24 and are guided rearwardly byslotted lugs 30 at the ends of frame I0.

Goggle frame Ill-is designed to be worn either with orwithout nose piece II. It is accordingly formed at the nose-receiving portion with a rearwardly projectingfiange portion 32 adapted to overlie and engage the nose of the wearer when nose piece is flnottusedc Ventilation .of the eyechamber is provided by means of a series of apertures 33in the top and sides of frame por tion.l5 located just behind sloping baiilemembers-34 The inner :surface of frame portion I5 is preferably lined with felt 35 or. any other suitable cloth material for filtering and diffusing air enteringthe eye chamber through ventilation ports 33. A particularly satisfactory material for this purpose is the clothsold under-the trade name Duv-atine. It is desirable to thicken frame portion; l5 .at 36 forpurposes of reinforcement.

Nose piece I l comprises a main body portion 40 defining a nose-receiving chamber and an outer layer or shield 42,- which is secured to the outer surface of element 4B. It is generallypreferred to form elements 40 and separately, as by molding from rubber :or-other suitable resilient material, and then securethem together as by any suitable adhesive alongthe periphery ofshield 42. It will be noted that shield 42 is formed with a more or less domed shape in such manner that it ismaintained in spaced relation with element 40 and thereby defines therewith a third or conduit chamber 44 overlying the nose chamber.

Communication between chamber '44 and thenose chamber is provided and controlled by mean of any suitable one-way valve assembly. Forexample, valve- 45 of soft rubber or like material is mounted by means of valve stem 46 in central rim 48 and ribs ill in the wall of element 40.

The function of this valve is to permit air to pass out from the nose chamber through apertures 62 between ribs 50. but to prevent the entry of the outside air into the nose chamber.

The rearward portions of nose'piece II are particuarly designed for engagement with the face of the wearer and with main frame l0. Frame portion 45 of nose piece I l extends into a top flange 64 adapted to overlie the nose of the wearer and two side flanges 65 adapted to engage the wearers cheeks. Lip portion 65 extends between flanges 55 and is adapted to engage the upper lip of the wearer and thereby to complete the sealing of the nose chamber from the outside atmosphere. At their forward surfaces, flanges 64 and 55 are so formed as to engage flange portions l6 and 32, and the lower portion of rim l2 engages the complementary groove defined by the domed configuration of shield 42 and flange 54. It will thus be seen that when the device is assembled in position on the face of the'wearer, the eye chamber is sealed from the nose and from the outside atmosphere except for air entering through ventilation ports 33, and the nose cham-, ber is similarly sealed except for air entering by way of conduit chamber 44 and valve 45.

The invention accordingly provides conduit means between the eye chamber and conduit chamber 44, and said conduit mean also funccloth serves both to filter and to diffuse the air entering the eye chamber, and it will be seen, therefore, that each time the wearer breathes he acts to evacuate and replace the air in the goggle eye chamber and thus prevents the accumulation of sufficient moisture therein to precipitate and foglens l4. V

The above described embodiment of the invention'is subject to' considerable modification without departing from within the scop hereof, In particular the construction of main goggle frame ID may be varied in many details provided it will still properly engage nose piece II and the wearer's face to provide the desired seal. The connecting means between frames 10 and II may similarl be varied widely, and it is to be expressly understood that tubes 12 are shown merely as an illustrative example of one operative form of connecting means. For example, in another modification there-may be used in place of each of tubes 12 a snap fastener element similar to elements 25 and 22 but comprising an elongated, open-ended male member and an open eyelet in place of the illustrated closed female member, The structure of nose piece H may be similarly varied without departing from the scope of the invention. For example, the invention is not limited to any particular structur or location for valve 45. Valve 55 may be dispensed with entirely, and the wearer may exhale through his mouth. In still another modification, nose piece ll may be extended to cover the mouth of the wearer provided the functions of the valves tion to secure main frame I5 and supplemental frame ll together. As is shown particularly in Figs, 1, 3 and 6, shield 42 is formed with a pair of bulb-like portions I5 so positioned that their upper surfaces will engage the lower surface of portion l5 of main frame Ill when the two frames are fitted together. Coincident holes are provided in each of these members at their points of engagement, and tube 12 of metal or plastic engage in these holes and are retained therein by annular shoulders 14 at each end thereof. In this manner tubes 12 serve both to secure frame In and nose piece I I together and also provide communication between the eye chamber and conduit chamber 44, The only modification of the main frame structure required for this purpose is to provide suiilcient slack in filter cloth 35 adjacent the apertures in frame portion l5 to accommodate shoulders 14 on tubes 12.

' It is believed that operation of the goggle of the invention will now be readily understood. When the main frame is worn without nose piece I I, it functions as a conventional goggle, and cloth 35 over the apertures in frame portion I5 for tubes 'IZserVes to prevent infiltration of dust or other particles. When it is worn with nose piece ll, each inhalation by the wearer will draw air from the outside atmosphere through ports 33 into the eye chamber, whenceit passes by way of tubes I2 into conduit chamber 44 and then by way of valve 45 into the nose chamber and wearer's nose. Upon exhalation the air passes into the outside atmosphere by way of valve 55 and is prevented by valve 45 from returning to conduit chamber 44 or theeye chamber. During this operation,

and the sealed connection to main fram 10 be maintained. In view of these and many other changes which may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that thefollowing claims are intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
